IMPROVEMENT IN HARVESTERS.

l Specification forming part of Letters Patent No. 20,050, dated April 27, 1858.

lo all rrhom it may concern:

Be it known that I, R. DUTTON, of Dayton, in the county of Montgomery and State ot' Ohio, have invented a new and useful Improvementin Adjusting the Platforms of Reaping and Mowing Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part or' this specification, in which- Figure l is a side elevation of a harvester with my improvement applied to it. Fig. 2 is a transverse section of the same. Fig. 3 is a side elevation of the same.

Similar letters of reference in each of the several figures indicate corresponding parts.

The nature ot' my invention consists in the employment ofthe loose hollow sliding sleeve between the hub ofthe driving-wheel and the shortaxle,in combination with the slotted segment provided on one ot' its inner sides with the cogs and adjustable axle having a pinion on its inner and screw-thread and adjusting jam-nuts on its outer end, the several parts bec et a; D E, gears for transmitting motion from propelling-wheel to mechanism which actuates the cutter-bar or other deiice. The inner end of the axle F of the wheel B is inserted through the curved slot C' of the segment-plate O, and is provided with a pinion, b, which gears with the teeth c, formed on one portion ofthe inner circumference ot said slotted segment, as shown clearly in Fig. 3. The outer end of the axle passes through a hollow loose sleeve or box, G, which is titted loosely in the hub of the Wheel B. This sleeve has a broad flange, d, on its inner end. Said liange has a guide-stop, e, formed on the center of its inner face. The ilange d bears against the outer face ofthe segment-plate, and serves as a steady-plate, and, in connection with the cog-pinion l), as a clamp, as presently described, while the stop e lits in the slot and serves as guide and steady pin. On the extreme outer end of the axle a sorew-thread,f,

is cut, and intermediate between this screwthread and the ends of the hub and loose sleeve the axle is made square, as shown at g. A plain jam-nut, h, tits the square g, and a screw-tapped nut, i, its the screw end f, as shown. A

From the above description of part-s it may be evident, if it is desired to raise the platform from the position shown in red in Fig. 1 to the position shown in black, that'by looseningthe screw-nut i with a wrench, and then applying another wrench to the jam-nut, the axle, with wheel B attached, can be easily run up to the desired position in the slot O thfough the aid of the cog-pinion b and cograck c, and after being properly adjusted can be locked in this position withoutjammingthewheelB by turning the wrench of nut i in an opposite direction to that in which li was turned and ceasing to turn the wrench of nut h, the locking being effected by reason of the inner face of the pinion jamming against the inner surface of the segment and the liange dup against the outer surface of segment, as may be evident from the drawings. The pinion has an independent longitudinal movementof the sleeve and liange, and therefore it is that it, as well as the iange, jams, said movement being imparted to the pinion by the nut t' and the movement of the sleeve and flange by the nut h. Itwill be observed that a sufficient space, j, exists between the driving-wheel and the ange to allow of these movements without liability of the motion of said wheel being cramped. With this simple arrangement the adjustment of thepla-tform or cutter-bar of reapers or mowers to any extent required can be effected with great ease, facility, and convenience.

What I claim as my invention, and desire to secure by Letters Patent, is-

The employment ot' the loose hollow sliding sleeve G between the hub of the driving-wheel and the short axle F, in combination with the slotted segment O on the side of the platform and the adjustable axle F, when the slotted segment is provided on one of its inner sides with the cogs c and the axle with pinion b on its inner and screw-thread f and adjusting jam-nuts h lon its outer end, the several parts being arranged to operate substantially as and for the purpose set forth.

R. DUTTON.
